摘      要：The deodorizer distillate(DD)is a byproduct of vegetable oil processing industry and is rich in functional bioactive *** study aimed to employ phosphorylation modification for DD to produce a new sustainable *** bioactive ingredients in DD,namely fatty acids,sterols,and tocopherols,were determined by using HPLC and *** results revealed that the DD sample contained a high percentage of unsaturated fatty acids(72.3%)and high levels ofγandδ-tocopherols(54.8%and 31.60%,respectively).Mechanical parameters(tensile strength,elongation at break,and tear strength)of leather were improved after being treated with the prepared fatliquor ***,SEM showed that the texture of the fatliquored leather had been remarkably ***,the fatliquored leather possessed effective antibacterial effect against the specified+ve,-ve bacteria,and Candida albicans *** strength,fullness,soft handle,and elasticity of leather were all improved,and the grain of leather was protected from becoming loose after drying.
